摘 要: | 提出了一种基于ETO控制的新型故障限流器(Fauh Current Limiter,简称FCL)。应用电力电子技术中的PwM(Pulse Width Modulation)控帝l技术对ETO发射极脉冲进行控制,通过改变占空比对FCL的阻抗进行调节,实现了可灵活控制的串联补偿和限流功能。在MATLAB/Simulink电气仿真环境下,对提出的FCL在配电馈线上进行了仿真。实验结果证明了发生故障短路期间新型FCL能在配电馈线上发挥限流作用,且可以通过改变占空比实现不同的限流效果,且FCL在配电馈线上的安装位置(相对于负载)对限流效果不会产生影响。

Abstract: | A new fault current limiter (FCL) controlled based on ETO is proposed. ETO' s emitter pulseis controlled by PWM control technology of power electronics, FCL' s impedance is adjusted by changingthe duty cycle, can choose the series compensation function and current limiting function flexibly. Then itpresents the fault short circuit simulation in the distribution feeder with the new FCL in MATLAB/Simulink for the electrical simulation environment. The experimental results show that the new FCL canlimit the fault short circuit current in the distribution feeder and can reach different limiting effects bychanging the duty cycle, then prove the installation location(relative to the load) of FCL is unrelated tothe limiting effect. |
